how to add rateLimit to graphql

[vowqg]

Hi,
I did a security test and the report showed two risks to the graphql API.

1. GraphQL Alias Overloading Allowed: Potential Denial of Service
   Vulnerability
2. GraphQL Array-based Query Batching Allowed: Potential Batching
   Attack Vulnerability

wikijs has a built-in graphql-rate-limit-directive, I wonder if it can solve these two problems with it?
